Norton 66253263465 Surface Grinding Wheel 60 Grit 12in

Product Description

The NORTON 66253263465 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability under continuous grinding loads. It measures 12 inches in diameter, 2 inches thick, with a 5-inch arbor hole, and carries a 60-grit, K-hardness (medium grade) specification rated to a maximum of 2070 RPM. The porous structure of the vitrified bond promotes coolant flow and chip clearance, reducing heat buildup during heavy surface grinding operations. Machinists, tool-and-die makers, and grinding technicians working on production surface grinders will find this wheel suited to demanding material removal cycles.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a broad range of material applications including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 60-grit medium-grade specification makes it appropriate for aggressive stock removal where surface finish is secondary to material throughput. It is sold individually and ships as a single unit.

Compatibility

Specified for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Mounting and dressing of grinding wheels must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Before mounting, perform a ring test to check for cracks and verify the wheel speed rating meets or exceeds the spindle speed of the machine. Power down and lock out the grinder before installing or removing the wheel. Always dress the wheel with an appropriate diamond dresser before the first cut to true the face and open the abrasive structure.
